The wiring harness coming from the solonoid/power distribution has one small guage wire splitting into three different medium guage wires. I have ran into this problem quite often on mustangs, and what I have found that works is take the split out of it, and run all three wires with fusible links added to them straight from the solonoid

Alternator fuseable link keeps blowing fuse at startyer solenoid


sounds like your altenator has a bad diode in it, causing the battery to have a big load on it and popping the fuse link.

MY 89 Ford Mustang GT did not pass smog because then Check Engine light DOES NOT light up. Would that be a fuse or bulb?


The light is controlled directly by the computer so if your car runs, it isn't a fuse. It just needs a bulb put in it.

Replace the flasher which is on the passenger compartment fuse block. It isn't like the old round ones. It is at the bottom.

Have a 1995 mustang gt where would my fusebox be located


The instrument panel fuse panel is located under dash (driver side) early brake.

The high current fuse panel is located in the engine compartment on the left-hand fender apron.

This is for one 1996 Mustang but can help like reference guide: 1996 Ford Mustang - Owners Manual (for FUSES, page 272 and next)

Hope help (remember comment and rated this).

1989 Ford Mustang no dash lights fuse blows when you go to high


I believe when you go to full brightness the dome light also turns on. If so check the dome light and door switches.
